Return a String[] from a WebService using NetBeans Ide

[luigi.tascapani]

Hi all, if I try to invoke a web service that return a String[] i have this error when i try to test it with netBeans:

Runtime exception; nested exception is: deserialization error: unexpected XML reader state. expected: END but found: START: item

When deployng WS.. JBoss console print out:

JavaWsdlMapping] Cannot find jaxrpc-mapping for type: {urn:NewWebService/types/arrays/java/lang}StringArray

I know it is a known problem but i haven't understand if someone solved it, and how.

The way to think about this goes like this:

1) Take a service endpoint interface (SEI)

public interface MyEndpoint
{
 String[] echoStringArray(String[] v)
}

2) Run a tool that generates wsdl + schema + mapping

 <complexType name="StringArray">
 <sequence>
 <element name="value" type="string" nillable="true" minOccurs="0" maxOccurs="unbounded"/>
 </sequence>
 </complexType>

 <message name=echoStringArray">
 <part name="arrayOfString_1" type="ns3:StringArray"/>
 </message>
 <message name="MarshallRpcServiceInterface_echoStringArrayResponse">
 <part name="result" type="ns3:StringArray"/>
 </message>

3) Look for the java mapping for that array type

 <java-xml-type-mapping>
<java-type>somepackage.StringArray</java-type>
 <root-type-qname xmlns:typeNS="{urn:NewWebService/types/arrays/java/lang}StringArray ">typeNS:StringArray</root-type-qname>
 <qname-scope>complexType</qname-scope>
 <variable-mapping>
 <java-variable-name>stringArr</java-variable-name>
 <xml-element-name>stringArr</xml-element-name>
 </variable-mapping>
 </java-xml-type-mapping>

4) Make sure the wrapper type is in your deployment

If you run wscompile with -keep, it keeps the generated java types

You could also have a look at

tdiesler@satellite /cygdrive/d/projects/jboss-branch/jboss-4.0.x/testsuite
$ ant -Dtest=webservice/marshalltest test

test:
 [junit] Running org.jboss.test.webservice.marshalltest.MarshallDocLiteralTestCase
 [junit] Tests run: 31, Failures: 0, Errors: 0, Time elapsed: 46.777 sec

 [junit] Running org.jboss.test.webservice.marshalltest.MarshallRpcLiteralTestCase

These tests marshall String[] as well

Thank's, i'll try the -kepp option, it's interesting.. to solve rapidely my problem I've made a MyStringArray class that contains a field value of type String[] and a get/set method. MyStringArray extends Serializable, and it works.

The problem is that WebService and all xml files to configure are so complexxx and I haven't so much time in these days.. But finaly i did it,
thanx
good bye
